Sheet metal processing is called sheet metal processing. Specifically, for example, the use of plates to make chimneys, iron drums, fuel tanks and oil cans, ventilation pipes, elbows and heads, rounded places, funnels, etc. The main processes include shearing, bending, bending, bending, welding, riveting, etc. Some knowledge of geometry. Sheet metal parts are thin-plate hardware parts, that is, parts that can be processed by means of stamping, bending, stretching, etc. A general definition is a part with a constant thickness during processing. Correspondingly, castings, forgings, machined parts, etc.

When processing hardware prototypes, different manufacturers make the same product, and there will be differences in accuracy. Because some purchasers know this, they will hand over the project to several different suppliers in order to find better suppliers. However, the number of each manufacturer is very small. After confirming which manufacturer has a higher accuracy, a large order will be placed. So, what causes these manufacturers to have differences in accuracy.

For sheet metal processing, the following types of CNC sheet metal processing methods are commonly used

1. One-time stamping, that is, one-time processing of stamping parts including: arc distribution, grid holes, etc.

2. Continuous blanking, divided into the same direction and multi-directional, the continuous blanking of the same direction is mostly processed by the method of die overlapping. For the processing of long holes, it is especially suitable for continuous blanking of multiple spinning positions. It is more suitable to use small molds for large machining of holes.

3. For encroaching processing, use circular die and small steps to do arc continuous punching processing.

4. One-time or continuous forming processing, single forming is to do shallow drawing and one-time forming sheet metal processing according to the characteristics of the mold, but if the forming exceeds the specifications of the mold, a continuous forming processing method is required.

5. Array forming, this type of extrusion forming method is suitable for the processing of several workpieces on a large plate, and the types of workpieces can be the same or different.

Hardware rapid prototype processing

1. The equipment used is different. Many hardware prototype processing factories cannot afford good equipment due to their limited strength. They can only use general equipment, so the processing accuracy will not be so high; secondly, in the process of processing, the cutting tool subject to a certain amount of wear and tear, they are not replaced in time, resulting in less accurate accuracy.

2. Differences in tool setting. For hardware rapid prototype processing equipment, there are two general methods of tool setting: manual tool setting and automatic tool setting. Presumably many people know that automatic tool setting is more accurate than manual tool setting, but In order to save costs, many small prototyping factories do not have a tool setting instrument on the purchased equipment, and can only manually set the tool, which affects the machining accuracy.

3. The operator's experience, generally experienced operators can detect various abnormalities in the process of hardware prototype processing early, and make adjustments in advance, so that the processing accuracy is slightly higher. The above are the reasons that affect the accuracy of the hardware prototype, I hope to help you.

The above are the common CNC machining methods in sheet metal processing, which are for reference only and hope to be helpful to everyone.
